How can you have an atmosphere compromised of 78 percent nitrogen 21 percent oxygen and 1 percent others with relative humidity of 4 percent?
When you see a list of the components of air, they refer to DRY air, because the amount of water vapor varies. If the relative humidity is 100% and the temperature is 104F, water vapor would make up 7% of that air. I doubt the dew point has ever hit 104F, so almost certainly it's never been that high and is usually a good bit less. When temperatures drop well into the double digits below 0, there is only a barely-detectable amount of water vapor. So those component lists floating around describes dry air, or the make-up of the air that isn't water vapor. Those numbers are fairly constant whereas if you tried to include water vapor, you couldn't come up with hard numbers because they are all displaced by any water vapor in proportion to how much of the dry air they make up.
What else can I help you with?
What do you call the water vapour in the atmosphere?
The water vapor in the atmosphere is referred to as "humidity." It represents the amount of water vapor present in the air and plays a crucial role in weather and climate patterns. Humidity can be expressed in terms of absolute humidity, relative humidity, or specific humidity, each providing different insights into the moisture content of the atmosphere.
What does the relative humidity have to be far a cloud to form?
Clouds can form at any relative humidity level, but typically they form when the relative humidity is close to 100%. This is when the air is nearly saturated with water vapor and begins to condense into liquid droplets, forming a cloud.
Which planet's atmosphere is mostly nitrogen and oxygen?
Earth's atmosphere is mostly made up of nitrogen and oxygen; but the planet itself is more than just its atmosphere - overall Earth, like other terrestrial planets, is mostly made from rock (silicates) with a nickel-iron core. (By comparison, overall the outer gas planets are mostly made from hydrogen and helium.) By relative abundance, oxygen is also the most common element in the Earth's crust.
How moist is the air?
The moisture content of air is typically measured using relative humidity, which describes how close the air is to being fully saturated with water vapor. High relative humidity indicates moist air, while low relative humidity indicates dry air.
Why is relativie humidity increased at night?
Relative humidity is typically higher at night because the temperature drops, which decreases the air's ability to hold moisture. This means that the existing water vapor in the air becomes more concentrated, leading to higher relative humidity levels.
What is the wetness of the atmosphere is called?
It is called the humidity of the atmosphere.
The amount of water vapor in the atmosphere is known as what term?
The amount of water vapor in the atmosphere is known as humidity. Humidity can be expressed as specific humidity, relative humidity, or absolute humidity depending on the context.
What is the difference between humidity and relative humidity, and how do they each affect the atmosphere?
Humidity refers to the amount of water vapor present in the air, while relative humidity is the ratio of the actual amount of water vapor in the air to the maximum amount it can hold at a given temperature. Both humidity and relative humidity impact the atmosphere by influencing weather patterns, cloud formation, and the comfort level of individuals.
What is the state if atmosphere with respect to moisture?
The state of atmosphere with respect to moisture is associated with humidity. As moisture saturates the air, it encourages a general increase in relative humidity.
What factors affect the relative humidity?
Just the quantum of moisture in the atmosphere, and its temperature.
What factors affect relative humidity?
Just the quantum of moisture in the atmosphere, and its temperature.
What weather factor is a hygrometer use for?
Hygrometers measure the relative humidity of the atmosphere. The relative humidity is the ratio between the present water vapor content of the air and the maximum amount of water vapor the air could hold at the same temperature. Cool air will not hold as much water vapor as warmer air. With the same amount of moisture in the air, an increase in temperature decreases the relative humidity, and if the temperature drops, relative humidity increases.
What terms indicates the moisture content of the atmosphere measured as a percentage of saturation?
relative humidity
What term indicates the moisture content of the atmosphere measured as the percentage of saturation?
relative humidity
What do you call the amount of water vapor in the atmosphere?
Relative humidity the exact amount of water vapor in the atmosphere (specific humidity)
Which is the comparison of the amount of moisture in the air to the amount of moisture it can hold?
relative humidity
